all whom it may concern:

Be it known that WILLIAM K. BAssroRD,

invented vcert-ain new and useful improve ments in lgniters for Engines,of which the following is a specification. l

, invention relates generally to means igniting internal combustionengine fuel, e id specifically to an improved device for automaticallyadvancing and retarding the .ligniting electric spark.

The-gener' "object of my invention is to `prevent;accidents' to theoperator, while the set fort-h as follows:- i, a generator armaturerospeciic ect As well.- kno tati-ng in-.fafmagiietic eld of force has acertain point of maximum voltage.

Heretofore, the timing of the' spark has been so arranged that the sparkwill occur at the point of maximum voltage, which point is shifted bymanual means forward or backward.

However, as the control is by hand, it may l 4easily bevperceived that.when ,the spark is at L. rIwo swinging weights dvanced ,*.t hen, unlessthe point of maxiigum voltagepf the armature isalsoadl iroughthe samenumber of degrees,the` des. d benefit 1s lost for the reasonthatthes'spark is not ofthe same intensity..A- As inaiageinent by hand isunsatisfactory and dangerous, l have invented means for accomplishingthe adjustment-s by the action of the rotating armature. i gain theresult that however farl the timing device is advanced, the armatureisadvanced angularly, through the saine number of degreessimultaneously, and the spark will always occur at the point of maximumvoltao'e.

'Figure l is an end view of the complete invention. Much of the `framework and casing and unnecessary elements for exhibiting the invention,are omitted. ifotted lines show hidden parts. Fig. @is the rear of thelower part of Fig. l. Fig. 3 is a side view of the invention. l? ig. 4shows a detail, with parts in section. Fig. is a face view the Contactplate.

rlhe arms l? and p radiate oppositely from a disk T, and are for thepurpose of b moved to change the angular posit armature with respect tothe shaft electric spark generator whose armat ilxed to gear wheels Rand R1, the arbors for the wheels being carried by the disk T. A gear onthe armature sleeve L1 meshes `with the gear wheels R and R1, theweights flying outward by the action of centrifugal force. is the disk Tis fastened rigidly to the shaft M, as the armature L is on the sleeveL1, which is loose on the shaft M, and

as there is a spring S1 connecting the arm P to the weight P1, and aspring S2 connecting the arm p to the weight P2, therefore, the higherthe rotary speed of the armature the greater the outward movements ofthe weights P1 and P2, and the greater the angular advancement ofthearinz'iture. V is another gear wheel fixed on the armature sleeve L1 andmeshing with the gear wheel H on which is mounted a timing device. thecentrifugal force, according to the speed, changes the angular positionof the armature L and sleeve L1, it also changes the angular position ofthe gear V, and therefore accomplishes the adjustment of the timingdevice with relation to the shaft M and the engine, as well as theadjustment of the armature to the point of maximum voltage.

rfhe timing device consists of the roller 2 rotating at the end of alever J which is pivoted to lugs 3 eccentrically located on the wheel H.

' el, e2, c3, e", are contacts arranged in a row around the axis ofthewheel H and in the path of the roller so that as the latter rotates,it wilt touchthese four contacts.

5 is a spring for pressing the roller 2 against the contacts.

Other parts shown in the drawing have nothing to do with the invention,vwhich is however defined as to its scope of novelty in the accompanyingclaim.

i claim as my invention;

ln an ignit 1r for internal. combustion engines, the combination of af'sleeve, an armature xed thereon, a driving shaft for the armaturepassing loosely through said. sleeve, a governor mounted upon saidshaft, and gearing between said sleeve and governor for permitting therelation between said armature and driving shaft to be changed.
